I went ahead and replaced my center support bearing on my driveshaft and while I was there, I replaced the 3 u-joints as well.
If anyone ever needs to replace the center bearing, here are a few tips.
1. After you have the driveshaft out and on your bench, just cut the old bearing off with a cut-off wheel. Just make sure you do not cut the machined surface of the d-shaft.
2. Before putting the new bearing on, put it in the freezer overnight. This will help it slide onto the shaft a little easier.
3. Take some spray lube and 220 or higher sandpaper and lightly smooth the machined surface (this will ensure everthing is smooth)
4. Have some large washers/steel plates handy to help BANG the new large steel cup on first.
5. You can use a piece of 1 1/2" PVC pipe to help drive the bearing on
6. Re-use the same washers/steel plates in #4 to drive on the small steel cup on last
